KNOCKDOWN FURNITURE.

Specification of Letters Patent.

Patented Mar. 18, 1919.

Application led December 16, 1918. Serial No. 266,880.

To all whom t may concern Be it known that I, CHARLES T. METZGER, United States, residirg at Chicago, in the conty of Cook and the tate of Illinois, have invented certain new and useful Improvements in Knockdown Furniture, of which the following is a specification, reference being had to the accompanyin drawings, forming a part thereof.

he purpose of this invention is to provide an improved knock-down construction of an article of furniture, such as a chair, rocker, davenport, sofa or the like. It consists 1n the elements and features of construction shown and described, as indicated in the claims.

In the drawings:

Figure l' is a fore-and-aft vertical section of the unupholstered frame `of a seatembodying this invention, the outlines of pos- Vsible upholstery being shown in dotted lines.

.'Fig. 2 is a front elevationof the back member frame, that is, devoid of upholstery.

Fig. 3 is a plan view of the seat box or frame of the seat devoid of upholstery.

Fig. 4 is a detail section at theline, 4 4, Fig. 5 is a detail section at the line, 5-5, on F1g. 4.

Fig.'6 is a detail on Fig. 1.

Fig. 7 is a detail section at the line, 7-7, on Fig. 1. U

Fig. 8 is a view similar to Fig. l, showing the modification of the connection between the end membersk andthe back member.

Fig. 9is a section atthe line, 9--9, on Fig. 8.

Fig. 10 is a detail section at the line, 10-10, on Fig. 8. i

The frame of the seat shown in the drawings consists substantially of four elements, namely, two end members, A, a seat box, B, and the back frame, C. Each of 'the end members comprises, with other members framed together for vertical rigidity, a vertically Hat fore-andaft extending bar, l, at the lower part, that is, at the plane of the seat, ,and the vertically fiat up-and-down exsection atthe line, 6 6,

tending bar, 2, which extends from the level of the seat box, B, as high as the endk members, kwhich are high enough to constitute or support arm rests, as indicated bythe dotted lines, a, at the upper end of the end' member,

bolts, 7-7, which shown in Fig. l. The seat frame or box, B, comprises vertically flat fore-and-aft extending end members, 3, 3, and vertically-flat longitudinallyextending front and back members, 4 and 5. The front and back inembers preferably extend slightly lbeyond the side members, as seen in Fig. 3. The seat box is adapted to be interposed between the two end members and bound securely thereto, the seat box constituting means of rigidly connecting together the two end members, and defining the erect position of the end members by the up-and-down-extending end edges of the front and back members-of the seat box which are clamped against the vertically-notched fore-and-aft extending bars, l, of the end member by means of clamping are anchored in one of the two connected parts, viz: seat box and end member, and extend through the facing element of the other member for receiving the clamping nuts, 8. As illustrated, and preferably. these bolts are anchored in the foreand project through the fore-and-aft-extendprotrusion of the bolts for receiving the nuts and of the nuts themselves is unobjectionable. Obviously, the positioning of the end members by the ends of the seat box may be regarded as effected by the verticality of the end members of the seat box generally, not limited to the verticality of the end edges of the front and back bars of said seat box; but the construction shown having the front and back bars projecting slightly beyond the end bars of the seat box is preferable, because the clamping bolts being positioned quite a distance inward from the corners of the box. the resiliency of the said end bars of the box is brought into play when Vthe bolts are tightened, and the reaction of these bars which are slightly sprung out of their plane in the tightening of the bolts, tends to keep the junction snug and free from shake notwithstanding the slight shrinkage of the wood which may occur, or its tendency to ybecome set in the compressed condition resulting from the tightening o'f the nut. The back member, C, comprises the vertically iiat 1up-and-down-extending end bars, 9, 9, which are adapted to seat ,-flatwise against the vertically iiat up-and-downene4 .and-aft-extending bar of the end member llower end of thel end bar, 9,

tending rear bars, 10, 10, .of t'lieend trame, These'lacing bars, 9 and'10, of the back member and the end members respectively,4 are engaged with eachother by projections and sockets Vontn'e two vacin'g members respectively, one such engagement being made at the lower part of the back ineinbemand the other at the upper part of tlieend member.

lower part of the back member is effectedbyf` a `tenon, 12, projecting from the end member bar, 10, engaging a socket-,13, near-the of the-back member; and the upper engagement is et# fected by means of a flat tenen, 15, preferably constituting one flange of an aii-gleiron, 16, whose other flange is boltedto lthe outer face of the rear bar-,'10, of the end member; and theend bar, 9, ofthe end memberhasa saw-cut slot,-9, into which the flange, 15, projects, said flange 'having a hole through which a screw, 17, screwed-into the rear end offsaidbar, 9, extendsfor cross-pinning the bracket securely in the back member bar, 9. lt will be seen that by this construction Athe end members are tied together atthe lower part by the seatbox, and .at the upper part by theback member, while` the back imember is secured a-gainstfore-and-aftfmoveinent be'rtweenthe two end'members by the ytenonand-soclret engagement ofthe back member with the end .members at the lower partv of the backmember.-

In the ymodifications shown in Figs. 8, 9

andlO, the baclmember -is joined at' its lower corners to the endlmembersbyangle iroirten-ons, 11G, each permanently secured by onefflan-ge to thefinnerf'ace ofl thelupand-down rear side bars of thefendmeinbers respectively, the otherlange .forming the tenoniand engagingasaw-ontslot, 9, inthe adjacent up-and-lownvend bar of theback member, and-.cross-pinnedl theslot by Va screw, 17 as` already described in respectto the similar engagement at the upper corner of the end members of the form shown in the earlier figures. In said modification o'flligs. 8,v 9V and 10, atthe upper'rearcornerof the end members, the rear side bars of said end members, whichralso constitute the-rear vlegs of thechair, abut against downwardly-'facing shoulders, 20, which jut off ,romtheouter 'face of .theenchbars of the back` mem-ber, and-ia tenonfand-socket engagement/is Aprovided-,between said upperV end olethe rear legv and=.tliefsa=id .do-Wnwardlyefacing shoulder of the back member, as seen' at 22 on Fig. v.10.
